I have been doing CP from past few months, and that too consistently(there is a break for 4-5 months in my rating graph, I was actively practicing during that phase, and wasn't giving contest, "because I lose my confidence").

But I haven;t seen much growth, I have seen people touching expert effortlessly with this much practise, "am I that dumb?".

Any advice for me on how to practice or something else, because I really wanna know where I am going wrong. :( Any kind of help/advice/suggestion would be highly appreciated.
